Features: the working voltage is 6-80V, and the anti-reverse connection protection is supported, and the module will not be damaged due to the power line reverse connection.The module is bare by default. If the motor is driven 5A current, it does not need to be forced to dissipate heat, but only needs to normal ventilation. If current exceeds 5A, it must be forced to dissipate heat.Board 5pin Hall interface, used to access the motor Hall signal.Onboard burning interface for updating the burning program.Onboard LED indicator for standby, working, error and other states.Onboard potentiometer (0.5~5V), PWM speed control interface (frequency 1~20KHz), duty cycle 10~100%.Onboard FG speed feedback interface, calculation speed RPM=FG frequency Hzx60/pole number.Onboard CW/CCW steering interface, suspended for clockwise CW, short-circuited GND for counterclockwise CCW steering.Onboard UART serial port. Users can control the module through the serial port protocol.Specifications: Operating voltage: 6-80VMaximum current: rated 20A 50AMaximum power: 1600WOvercurrent protection: yesMotor drive baseThere is hall starting and commutating bottom layerPhase compensation algorithmVelocity closed-loop algorithmCurrent limiting algorithmDownwind start-up algorithmApplications: Pumps, all kinds of compressors, all kinds of fans/fans, electric screwdrivers, electric curtains, automatic doors, hydraulic oil pumps, air pumps, refrigerators brushless DC compressors, lawn mowers, sprayer, underwater thrusters, etc.Material: PC+Metalcolour: BlackPackage Contents: 1 x DC Brushless Motor Controller(Due to different product batches, the appearance may be different, which does not affect use)Only the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
